in height. A retaining wall having solid 

 earth on one side affords better advan- 

 tages for the growing of plants than one 

 where each side is a " garden," for natu- 

 rally in the latter case, the storage space 

 for plant food is limited. Better results 

 are obtained when the face of the wall 

 slopes back from the perpendicular. 



Further details of a Wall Garden and 

 directions for planting, etc., may be found 

 in another book of this series entitled 

 "Making a Rock Garden" by H. S. 

 Adams. 



BRICK WALLS 



Perhaps there is no building material 

 better than good, hard burned bricks. 

 They have had the test of time such as no 

 other material made by man has had. 

 They have wonderful variation of color, 

 a pleasing range of surface textures and 

 when laid up in cement mortar a perma- 

 nency that not even stone can exceed. 

 Coming in regular sizes, a wall of them 

 may be of any thickness provided the di- 

 mension is a multiple of four, the depth in 

 inches of the average brick.
